Short answer: YES but in Ubuntu 11.10 and up which will come in 1 or 2 days. It will come with unity and you can install via the Software Center the package gnome-shell
(Which some wrongly call gnome3 or gnome3.2). After installing it just logout and you should see in the login both of them (unity and gnome-shell)
If you can wait a couple days, this will be a whole lot easier after you upgrade to 11.10. Just search for and install "gnome-shell" in the software centre.
